The Stretch release is the first version of Debian to feature the modern branch of GnuPG in the gnupg package. This brings with it elliptic curve cryptography, better defaults, a more modular architecture, and improved smartcard support. We will continue to supply the classic branch of GnuPG as gnupg1 for people who need it, but it is now deprecated.Administrators and those in security-sensitive environments can be comforted in the knowledge that the X display system no longer requires root privileges to run.The UEFI (Unified Extensible Firmware Interface) support first introduced in Wheezy continues to be greatly improved in Stretch, and also supports installing on 32-bit UEFI firmware with a 64-bit kernel. The Debian live images now include support for UEFI booting as a new feature, too.
